Messier 106 (also known as NGC 4258) is an intermediate spiral galaxy in the constellation Canes Venatici.It was discovered by Pierre Méchain in 1781. M106 is at a distance of about 22 to 25 million light-years away from Earth.
Messier 100 (also known as NGC 4321 or the Mirror Galaxy) is a grand design intermediate spiral galaxy in the southern part of the mildly northern Coma Berenices. [5] It is one of the brightest and largest galaxies in the Virgo Cluster and is approximately 55 million light-years [ 3 ] from our galaxy , about 166,000 light-years in diameter.
M22 is one of only four globulars of our galaxy [c] known to contain a planetary nebula (an expanding, glowing gas swell from a massive star, often a red giant). It was an object first noted of interest using the IRAS satellite by Fred Gillett and his associates in 1986, as a pointlike light source [ d ] [ 16 ] and its nature was found in 1989 ...

Our own galaxy, the Milky Way, is a large disk-shaped barred-spiral galaxy [92] about 30 kiloparsecs in diameter and a kiloparsec thick. It contains about two hundred billion (2×10 11 ) [ 93 ] stars and has a total mass of about six hundred billion (6×10 11 ) times the mass of the Sun. [ 94 ]
2005 – Spitzer Space Telescope data confirm what had been considered likely since the early 1990s from radio telescope data, i.e., that the Milky Way Galaxy is a barred spiral galaxy. [14] [15] 2012 – Astronomers report the discovery of the most distant dwarf galaxy yet found, approximately 10 billion light-years away. [16]
The word galaxy is derived from the Greek galaxias (γαλαξίας), literally "milky", a reference to the Milky Way. Galaxies range in size from dwarfs with just a few billion (109) stars to giants with one hundred trillion (1014) stars, each orbiting its galaxy's center of mass.
